FAQ

What is the molar mass of Cu?

M(Cu) = 63.546 g/mol

How is the molar mass of copper different from its atomic weight?

Only in units: the relative atomic mass Ar(Cu) = 63.546 has no unit, and the molar mass M(Cu) = 63.546 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of Cu?

m = n × M = 2 mol × 63.546 g/mol = 127.092 g.
